Wildfire smoke presents a serious health concern. One in three households in the United States has someone with a respiratory condition such as asthma or emphysema. Wildfire smoke is a mixture of gases and fine particles, which can irritate eyes and respiratory systems and aggravate chronic heart and lung diseases. Researchers at the PNW AirFire Team work to provide fire managers with technical information they need about smoke dispersion. For example, where could the smoke plume be going, and how thick could the smoke be? Their air quality modelling is a critical tool for technical specialists called Air Resource Advisors (ARAs), who assist the interagency support teams that organize firefighting activities, known as incident management teams. The ARA focuses on addressing the smoke impacts of wildfire. The ARA provides information on smoke dispersion and air quality effects, collects and disseminates monitoring data, and works closely with the incident management team and state and local air quality and health agencies to communicate potential health and transportation safety impacts for firefighters and the public. AirFire helps serve up the technical information the ARAs use, working closely with them on active wildfires. Air Resource Advisors are a key component supporting the Wildland Fire Air Quality Response Program—a nationwide interagency effort dedicated to addressing the smoke impacts of wildfire.
